Window Door Contact Sensor Eltako FTK-wg — white glossy surface, magnetic reed contact

Eltako FTK-wg is a compact window and door contact sensor with a white glossy surface and a magnetic reed contact designed for reliable detection of open and closed states. Intended for integration with alarm systems and home automation controllers, the sensor provides a simple electrical signal when the magnet moves relative to the housing. Its low-profile housing and straightforward mounting options make it suitable for use on inward- or outward-opening windows and doors where discreet position monitoring is required.

Advantages

The FTK-wg offers dependable magnetic reed technology that delivers a clear binary state for intrusion detection and position reporting. Its glossy white finish blends with modern interior fittings while the compact form factor minimizes visual impact. Installation is straightforward and requires only basic tools; the sensor provides consistent contact switching with low power requirements, making it compatible with a wide range of security and automation systems.

Suitable for

• Residential and commercial window and door monitoring
• Integration with alarm panels and security systems
• Home automation scenarios for presence, ventilation, or lighting control
• Retrofit installations where minimal visual intrusion is desired

Key specifications

• Type of sensor: magnetic reed contact
• Housing color and finish: white, glossy
• Form factor: compact, surface-mountable housing
• Detection: open/closed (binary contact state)
• Mounting: designed for window and door frames, flush or surface mounting
• Electrical interface: dry contact suitable for alarm and automation inputs

How to use

Position the sensor body and the magnetic actuator on the fixed frame and moving sash respectively, keeping the recommended alignment and gap for reliable contact operation. Secure both parts using screws or adhesive as appropriate for the mounting surface. Connect the sensor’s switching contacts to the alarm panel or automation input following the system manufacturer’s wiring diagram. After wiring, test the open and closed positions to confirm correct signalling and adjust alignment if necessary.

Usage recommendations

For reliable operation, mount the sensor on clean, dry surfaces and avoid locations where strong external magnetic fields or metal obstructions could affect the reed contact. Verify compatibility with the control panel’s input type (normally open/closed) before installation and perform functional tests after installation and during routine maintenance checks.
